42CrMo steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue limit and multiple impact resistance after quenching and tempering. It has good low-temperature impact toughness and high creep strength and durable strength at high temperatures.

Principal Feature:
42CrMo steel is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue limit and multiple impact resistance after quenching and tempering. It has good low-temperature impact toughness and high creep strength and durable strength at high temperatures.
Typical Application:
42CrMo is suitable for manufacturing large and medium-sized plastic molds that require a certain degree of strength and toughness. It is used to manufacture important parts that require higher requirements or larger cross-sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, load-bearing poles, etc. Large connecting rods, spring clamps, drill pipe joints and fishing tools for 1200~2000m deep oil wells, etc.
Heat Treatment:
Heating temperature 1150~1200°C, start temperature 1130~1180°C, end temperature >850°C, slow cooling when φ>50mm
